Hi,
We loaded the attached TCS file in TICS Pro. But the IN1 was not driven by any clock.
So the expectation was that LOL_PLL1, LOPL_DPLL1, LOFL_DPLL1, LOL_PLL2, LOPL_DPLL2, and LOFL_DPLL2 will be ticked on the Status&Interrupt page.
But none of them are ticked. So what might be the issue?
Hello,
There are a few contradicting statements here which I think has to stem from just not correct way to communicate things..
You mention none of the flags are ticked yet in the following sentence also mention some flags that are checked and how things change when you perform a read status. So let's clear up a few things.
But if I click "Read Status Regs" or "Read Status", all flags are cleared and DPLL1_REFSEL_STAT and DPLL2_REFSEL_STAT are updated as "Holdover".
So again here, what the status shows after loading the .tcs is irrelevant. In order to know the true status of the device you need perform a status read. Seems like when you do a status read you see device correctly being in holdover with no reference provided. This is expected behavior. LOPL_DPLL and LOFL_DPLL should also be flagged.
With regards to OUT7 I would disable and powerdown the channel although simple disable should work. Make sure to do this on the Advanced Output tab and not the Main Start page tab. The main start page is meant to generate the configuration and not necessarily used for active updates.
Furthermore, just to make sure here, a runscript was done after the inputs provided on the main start tab, correct?
Lastly, missing clock and late detect should be enabled for all configurations.

Hi Amin,
I will explain what I did to avoid confusion. The IN1 was not driven by any clock while doing the below exercise.
3. Now I clicked "Run Script".
4. After the registers are updated, I clicked "Read Status" as well as "Read Status Regs".
Below is the screenshot of the Status&Interrupt page.
5. Then I clicked "Soft-reset Chip" and read the status. But there was no difference in the
status.
Is this the expected behaviour?

Hi Ranjith,
Thank you for the details and images. It's much easier to follow this way.
When runscript is run, a soft reset should always be performed. So we will only focus on the results after the soft reset.
In first step, when you say loaded the .tcs file, this is your own file that you have generated previously, correct? Did this file work accordingly at any point? Please note we always recommend to start with EVM default configuration (found under Default configuration --> EVM default) and then start making changes there. There are registers that runscript doesn't touch and it's important that they were set correctly to begin with. Initial install of TICSpro and load of the device profile may not necessarily do this.
Even focusing on just your post runscript status read - device behavior does not match.
This is not how it should behave nor how I have seen it behave. Can we go back to default EVM configuration and see if these flags go up? Your physical configuration (EVM setup/connections) is something else so even if IN1 is provided or isn't provided the flags corresponding to no valid reference and DPLL LOL should go up.
There are 2 other ways to read the status registers just in case there's some kind of GUI interaction that is causing the actual issue. First off you have mentioned that you had done both "Read Status Regs" and "Read Status", I'm just highlighting below to confirm because I know on one of our devices one of these buttons did not work and I'm not certain if this has been fixed yet or not, so here are the buttons:
You can also try a "Read all registers" - 2 to the left of Read Status Regs.
The other location that status registers appear in case this is a GUI issue is under the user controls tab - status section (remember after soft reset and read all registers):
The 2nd place, is to read the raw register. If you hover over the section you'll see in the text context box on the left side you will see register information - this is true of any section within TICSpro. Under Raw Register tab please readback R14 and R15 the corresponding status registers for DPLL/APLL1 and DPLL/APLL2 - the GUI shows a 0h readback when we know the LOPL, LOFL, and Holdover bits should be on. Click anywhere within the register line and then click read register:
Hopefully with these steps we can get closer to what's happening. To me, it seems like those sections of the status reads just aren't updating which is bizarre.

Hi Amin,
The .tcs file that I load was working earlier.
I have ensured a Soft-reset Chip is performed before checking the status while executing below tests.
First Test:
- Clicked Default configuration --> EVM Default
- Clicked Update Frequency Plan
- Clicked Run Script
- Clicked Soft-reset Chip
- Clicked Read Status/Read Status Regs
Observation:
- LOL_PLL1, LOPL_DPLL1, LOFL_DPLL1, LOL_PLL1, LOPL_DPLL1 and LOFL_DPLL1 are not flagged
- DPLL1_REFSEL_STAT and DPLL2_REFSEL_STAT are Holdover
Yes, I clicked Read Status/Read Status Regs as you highlighted in the screenshot.
I tried "Read all registers". The observation is same as above.
I checked the status under Use Controls tab, STATUS section. None of the flags are ticked.
Below is the screenshot of the Raw Registers tab.
I am attaching the register map exported at this point.

Hello Ranjith,
You have indicated everytime that LOL_PLL1 and LOL_PLL2 are not flagged - why is this important? If the XO input is being driven, then these shouldn't be flagged irrelevant of IN_x status. IN_x drives the DPLL, XO input drives the APLL. LOL_PLLx flags are just for the APLL so as long as XO is provided and the correct configuration, it will be locked.
Can you confirm you're using the latest version of TICSpro?
Can you disable the XO being driven in any way? That way we'd at least be able to see LOL_PLL1 and LOL_PLL2 being triggered.
Actually, on the XO topic, are you using a TCXO by any chance? What is the ppm stability of the XO that you're actually using? Note LOL DPLL flags are tied PPM, so if you're using an XO reference that has very low ppm - like a TCXO - the flag may show you a Lock status even for DPLL. But even in that cases the phase (LOPL_DPLLx) would not be locked as for the phase to lock the R div path (from reference) and N div path (feedback from the VCO) need to be in phase.
These are the signals from the Rdiv and Ndiv path, when DPLL is locked they will be either in phase or 180 phase shifted. During lock procedure you will see them move to achieve this. If IN_x is not being driven then there should be no signal on the Rdiv path.
This is a flag issue - there's no way that the DPLL is actually locked if there's no input on the IN_x irrelevant of configuration. The only thing I can think of is if an older version of TICSpro is being used.

Amin
